Cenergy Co completed a solar power plant with an output of about 18MW at Nagato Farm in Nagawa-machi (town), Nagano Prefecture, Japan, Jan 2, 2018, and started power generation.

Cenergy (Nagoya City) is a company that is affiliated with the Chubu Electric group. The amount of electricity generated at the mega (large-scale) solar power plant is equivalent to the amount consumed by 5,200 households.

Cenergy set up about 72,000 solar panels on about 33ha of land that had been unused because it is not suited for harvesting pasture grass. The solar panel and PV inverter employed for the plant are products of China-based Astronergy and Toshiba Mitsubishi-Electric Industrial Systems Corp (TMEIC), respectively.

The plant is Cenergy's 10th mega solar plant in Nagano Prefecture and one of the company's largest-scale solar power plants. Toenec Corp (Nagoya City), which is affiliated with the Chubu Electric group, provided construction services for the plant. Electricity generated at the plant will be sold to Chubu Electric Power Co Inc for 20 years.

Nagato Farm is a farm run by a semi-public corporation and invested in by Nagawa-machi. On the premises of the farm, there is also NTT Facilities Inc's 4.2MW solar power plant.

The farm expects to receive about ¥50 million (approx US$454,545) by leasing the land to the two mega solar plants and use it for renewing and expanding facilities for growing cows and producing dairy products.
